Performance Upgrade. If your 1979 to 1993 Foxbody's 5.0L engine is sporting some bolt-ons or even a forced induction setup, you need a pair of Moser Axles to be able to light 'em up without worrying about your weak OEM axles.

Street and Strip. If you have a heavily modded street or strip Pony, your stock 28 spline axles might be too weak to take the heat. These premium quality forged steel axles have 31 splines to ensure all your power and torque are transferred straight to the pavement - where it belongs.

Built to Perform. Moser Engineering 31 Spline Forged Steel axles are made with some of the toughest, strongest, most durable materials available. These axles feature machined C-Clip grooves to fit OEM application 8.8 inch rear ends. They are non-tapered and also feature hardened bearing seats for durability and performance under high stress conditions.

Customize. Moser Axles feature the ability to be shortened and resplined if you decide to narrow your rear at a later time.

Application. This pair of Moser Engineering Forged 31 Spline Axles is designed for 1979-1993 Mustangs with the 5.0 engine and 5 lug wheels.

Got these for my 5-lug 31-spline swap. They went in perfect and sealed up right. Didn't get to finish the swap before I left to Afghanistan so I'll have to update on the details and fitment later. As long as they clear and fit well with my new 17x9 Bullit rims and a 5-lug rear break upgrade I'll be 100% satisfied!
